Transparent GIF Animation Decoding

This was a long time. I had very much to do in my job and 3 weeks vacation. I also was kind of stuck with a problem while decoding animated GIFs with alpha transparency. The decoder did not want to return proper alpha values. So, I stepped deep inside the GIF decoder and prepared myself to add the missing function. But tonight I discovered the method"CxImage::AlphaFromTransparency", which did the job. Yes, the project takes much longer, than expected because of day time work. But it is still alive.
